Definitions
- the present disclosure relates to lens holding apparatuses, and particularly, to a lens holding apparatus capable of holding a number of lenses by way of suction.
- Lenses are widely used in cameras and other optical devices. Usually, an injection molding method or a press-molding method is used for molding a large quantity of the lenses in a single batch. After the molding, the lenses may have to go through other treatment processes, such as surface cleaning and film coating. As such, lens holding apparatuses are needed to carry the lenses to a location of the next process and/or to hold the lenses during the next process.
- a typical lens holding apparatus includes a main body and a cover.
- the main body has a number of recesses formed in a top surface thereof, and the cover has corresponding through holes.
- the lenses are disposed in the respective recesses, and the cover is disposed on the main body, with an optical surface of each of the lenses extending through the corresponding through hole.
- the lens holding apparatus holds the lenses.
- the size of the lenses may not conform to the sizes of the recesses and the through holes. In such case, the lenses may vibrate in the lens holding apparatus. That is, the lens holding apparatus cannot steadily hold the lenses.
- FIG. 1 is a schematic, isometric view of a lens holding apparatus in accordance with a first embodiment, the lens holding apparatus including a pipe and a number of lens holding units.
- FIG. 2 is a cross-sectional view of the pipe and part of one of the lens holding units of FIG. 1 , taken along line II-II thereof, and also showing a lens held by the lens holding unit.
- FIG. 3 is a similar to FIG. 2 , but showing a pipe and part of a lens holding unit of a lens holding apparatus in accordance with a second embodiment.
- FIG. 4 is a similar to FIG. 2 , but showing a pipe and part of a lens holding unit of a lens holding apparatus in accordance with a third embodiment.
- the lens holding apparatus 100 is capable of holding a number of lenses 16 , and includes a pipe 11 , a number of lens holding units 10 , and an air pump 20 .
- Each lens 16 includes a central optical portion 161 and a peripheral portion 162 .
- the central optical portion 161 has a convex optical surface 163 on the top, and a flat optical surface 164 on the bottom.
- the peripheral portion 162 has flat surfaces (not labeled) on both the top and the bottom.
- the pipe 11 has an airtight end 112 and an air vent end 114 at opposite extremities.
- the airtight end 112 is a sealed end of the pipe 11 .
- the air pump 20 is connected to the air vent end 114 .
- the lens holding units 10 are arranged on a same side of the pipe 11 , and are parallel to each other. In the illustrated embodiment, a hollow end of each of the lens holding units 10 is integrally formed with the pipe 11 . Thus, the end of the lens holding unit 10 is in communication with the pipe 11 .
- the lens holding unit 10 includes a number of first portions 101 and a number of second portions 102 . The first portions 101 and the second portions 102 are alternately arranged in a line.
- the second portions 102 are arranged in a line along the direction A.
- the second portions 102 are arranged in a regular m ⁇ n matrix array.
- the first portions 101 are substantially rectangular shaped, and the second portions 102 are substantially cylindrical shaped.
- Each first portion 101 has an inner space 123
- each second portion 102 has an inner space 124
- the inner spaces 123 , 124 communicate with each other.
- the inner spaces 123 of the first portions 101 are intercommunicated by the inner spaces 124 of the corresponding second portions 102 .
- Each second portion 102 includes a top wall 121 and a bottom wall 122 .
- the top wall 121 has a first through hole 141 formed in a central region thereof.
- the first through hole 141 has a constant diameter, which is preferably substantially equal to or slightly greater than that of the lens 16 .
- the first through hole 141 is in communication with the inner space 124 .
- the bottom wall 122 has a second through hole 142 formed in a central region thereof. A diameter of the second through hole 142 is less than that of the first through hole 141 .
- an axis of the first through hole 141 , an axis of the second through hole 142 , and an axis of the second portion 102 are all coaxial with one another.
- a ring-shaped supporter 15 which is made of airtight material, is attached to the bottom wall 122 in the second through hole 142 and further extends into the inner space 124 .
- the ring-shaped supporter 15 can be attached by means of, e.g., interferential engagement or adhesive.
- the lens 16 is received in the first through hole 141 , and is disposed on the supporter 15 .
- the optical surface 163 is exposed to the outside of the top wall 121 . With this configuration, various treatment processes, such as surface cleaning, can be easily carried out on the optical surface 163 .
- the optical surface 164 can be exposed to the outside of the top wall 121 , such that various treatment processes can be carried out on the optical surface 164 .
- a porous wick structure 13 is arranged in the inner spaces 123 , 124 , around the lens 16 and the supporter 15 .
- the porous wick structure 13 can abut a periphery of the lens 16 .
- the porous wick structure 13 contacts the periphery of the lens 16 .
- Air can go through the pores of the porous wick structure 13 .
- the inner spaces 123 , 124 form a low air pressure chamber, and an annular interface 140 between the lens 16 and the supporter 15 becomes airtight, such that the lens 16 can be steadily held in position.
- the air pressure of the inner spaces 123 , 124 increases until it is the same as the air pressure of the outside (ambient) environment. At that time, the lens 16 can be released from the first through hole 141 .
- an exemplary lens holding apparatus 200 in accordance with a second embodiment is shown.
- the lens holding apparatus 200 is similar to the lens holding apparatus 100 described above.
- a top wall 221 has a step-shaped through hole 241 formed therein.
- a lens 26 is retained on an annular inner step 240 of the through hole 241 .
- a porous wick structure 23 is arranged in an inner space 223 and substantially an entirety of an inner space 224 .
- FIG. 4 an exemplary lens holding apparatus 300 in accordance with a third embodiment is shown.
- the lens holding apparatus 300 is similar to the lens holding apparatus 100 described above.
- a supporter 35 is integrally formed with a bottom wall 322 and also configured to support a lens 36 .
